I have the phone cable running from the phone (AT&T DECT 6.0) to the obi200 but the jack only flashes green, even when I unplug the cable from the obi200 it still flashes green. I can't even do the test call. The ethernet and power jacks are solid green. I don't know how to resolve this.
thanks
1. Help yourself to get help by trying to use accepted terminology. Jacks do not flash.
2. Try a factory reset.

3. Is this a brand new OBi200 obtained from a reputable seller?
